AAT1 — Brassica oleracea var. botrytis

Summary

BoAAT1 (AAT1) on chromosome 7 of cauliflower encodes a protein with a CAT_C domain and an AA/rel_permease1 domain, and has been annotated with L-lysine, L-glutamate, and basic amino acid transmembrane transporter activities. The gene is associated with basic amino acid transport and L-arginine import into the cell, and its product localises to the membrane, plasmalemma, and cytoplasm. BoAAT1 is associated with chlorophyll fluorescence, resistance to Pseudomonas syringae, flowering time, and plant biomass. Studies of related genes in other species connect the family to salt tolerance, oxidative stress tolerance, high-light stress tolerance, cadmium tolerance, and pathogen resistance, and to amino acid transport.
